Linking a static (.a) library to a common (.so) library, receiving the error "move R_X86_64_32S against a local character, recompiling with -fPIC"

Compiling with g ++ 64-bit in redhat using eclipse.

Compilation error: .. / lib -EL5-64bit / libskd3_clnt_30134500.a (skd_clnt.o): moving R_X86_64_32S against the "local character" cannot be used when creating a shared object; recompile with -fPIC

Things I tried I added -fPIC for both C ++ compiler flags and linker flags. It already exists in the compiler flags, I just moved it directly after g ++ and at the end of the list.

I asked the creator of the .a library to recompile with -fPIC and it still gives the same error

Is there any way to make sure their library has been compiled with -fPIC? Does the error message tell me that I need to compile my .so with -fPIC, or do I need to compile the .a file with -fPIC? What else can I check?

Here is the make file (automatically generated by eclipse)

When you compile statically, assembler instructions will take on some things about code locality, for example. any jump is within 4 GB of the jump / challenge command. (Assume 64b x86). Shared libraries can be loaded further than 4 GB, so the jump / challenge will not match.

-fPIC ( ) - , , / / (, 64b).

, , - . - -fPIC. (, 32- 5 , 9 [1 + 8 addr], - , , INT ).

/ -fPIC , - .
